Im trying to a equip a gun tool and it teleports me to it how do i fix that?

I have tried welding it but there is no handle and it still teleports me to the place it was put away at here is the tool https://www.roblox.com/library/4455573346/Kar98K-Working

the problem is that the item is anchored and it has to be un-anochored. btw i tested the model https://www.roblox.com/library/4455573346/Kar98K-Working and i couldnt take it so i renamed a part to 'handle' and unanchored the tool
